Proline hydroxylase for collagen
WebProline residues in the collagen proteins can be hydroxylated in the endoplasmic reticulum by collagen prolyl 4-hydroxylase or prolyl 3-hydroxylase in the presence of oxygen, ascorbic acid, α-ketoglutarate, and Fe 2+ (Gorres and Raines 2010).The ratio of 4-hydroxyproline to 3-hydroxyproline in collagen proteins is approximately 100:1.

WebAug 18, 2013 · There are a dozens of collagen variants found in our connective tissues and cells. It is composed of three repeating amino acids of the form glycine-X-Y. X and Y often include proline or a derivative of proline, hydroxyproline. X and Y are less commonly other amino acids such as lysine, hydroxylysine, or histidine. WebProlyl 4-hydroxylase (EC 1.14.11.2) catalyzes the formation of 4-hydroxyproline in collagens by the hydroxylation of proline residues in X-Pro-Gly sequences. The reaction requires Fe2+, 2-oxoglutarate, O2, and ascorbate and involves an oxidative decarboxylation of 2-oxoglutarate. Ascorbate is not co …
